Abstract
A bi-component fiber is provided. The bi-component fiber includes a sheath formed of polyphenylene sulfide (PPS) and a core formed of a high glass transition polyester. A PPS material of the sheath has a higher melting point than a high glass transition polyester material of the core. The core is at least partially crystallized whereby the high glass transition polyester material of the core effectively has a higher softening point than a softening point of the PPS material of the sheath.
